The KLVP5 is primarily designed as a diaphragm vacuum pump. Although positive-pressure performance is listed in the manual, continuous positive-pressure operation is not recommended because it may shorten product life.
Performance data were measured using air at 25°C and standard atmospheric pressure without load. Actual flow, vacuum, noise and service life may vary with system resistance, environmental conditions, gas properties and duty cycle. Application testing is recommended before final OEM integration.
